Someone on FABO ID'd these as - 70-71 383 2 barrel (non HP) 1.863 compression height.
I have not yet been able to confirm this.

The L2315F Pistons that they still sell have 1.92 compression height.


That is the tallest available aftermarket 383 piston , sold I believe as an NHRA replacement , it's as heavy as a stock cast piston except it's forged.

running up my post count some more .
